ABSTRACT:
A method for dynamically controlling the number of servers in a transaction system comprising at least one service unit for processing service requests is disclosed. Each service unit comprises a queue for receiving and queuing the incoming service requests and a plurality of servers for executing the service requests. The method comprises a first step of monitoring the current number of service requests and the current number of servers allocated to each one of the service units, a second step of determining an optimized number of servers for each one of the service units dependent on the current number of service requests and the current number of servers, and a third step of allocating the optimized number of servers for each one of the service units.
